• Windows 8 will not load color profiles - why?

  - by Fusilli Jerry

  I have a Spyder3Express color calibration device. Under Windows 7 the utility that came with it would happily load the custom profile I created with it without any hassles. Under Windows 8 (have just upgraded) there is no visible color shift when it says it has loaded the profile. I have gone into the Windows color management settings and when I select any profile and hit 'Set as Default' nothing happens. They all look the same. So Windows doesn't throw an error, but none of the profiles cause any color shifts at all. I have tried a large number of things, such as changing the global color settings for all user accounts and installing other color management software to see if it will load the profiles. The only way I can get a color shift is if I create a profile using Windows built in utility. Profiles created this way change the appearance of the screen, but any downloaded or created profiles make no difference. I am out of ideas. Please help :)

• SPF include: too many IP addresses

  - by sprezzatura

  I've hit a snag with SPF. The SPF record for my domain will contain four or five entries, plus it will contain: include:sgizmo.com The SPF record for sgizmo.com contains eleven entries! This, plus mine, is way over the maximum ten allowed by the RFC (and probably by most servers). I realize that there has to be a limit in order to prevent DoS attacks. However, in the real world, it is probably not unreasonable for large companies to have many server addresses. Furthermore, must I know monitor my 'include:' counterparts for changes and additions? Must I check weekly, daily, to insure that some combination of changes doesn't suddenly put me over the top? It doesn't seem to me that SPF is suitable for prime time. Is there another way to do this?

• Error while setting up Anywhere Access on Windows Server 2012 Essential (personalized domain name from Microsoft)

  - by Thomas

  I am trying to setup Anywhere Access on a Windows Server 2012 Essential Release Candidate, but keep getting this error: "The domain name was not setup for your server. Wait a few minutes and run the wizard again. An unknown error occurred. Please wait a few minutes and then try again". These are the options that I selected in the Wizard: I want to set up a new domain name Get a personalized domain name from Microsoft Entered my Windows live id and password xxxx.remotewebaccess.com And on the next page the error is displayed. I have setup my router (Linksys WRT160N) to forward all TCP traffic to the Server. UPnP is also enabled. If I hit my public (dynamic) IP (http://188.182.194.182/) I get the Windows Server 2012 homepage. Any ideas?

• Why does Tomcat try to use the cache when compilation failed?

  - by etheros

  For some reason, it appears Tomcat is trying to hit its compilation cache when compilation failed. For example, if I create a JSP containing nothing but Hello, <%=world%>!, predictably, I get an error: org.apache.jasper.JasperException: Unable to compile class for JSP. Subsequent requests however alternate between this and org.apache.jasper.JasperException: org.apache.jasper.JasperException: Unable to load class for JSP. Further, if I create a JSP containing Hello!, it of course works just fine. If I modify it contain Hello, <%=name%>!, the response alternates between the previously-mentioned compilation error, and the cached Hello!. What's going on?

• How to make Google Chrome honor my Windows dpi setting?

  - by Ian Boyd

  Google Chrome doesn't seem to respect my dpi-setting in Windows. i run at 150 dpi, but Chrome ignores that; meaning that images and text are teeeeeeny tiny. i hit Ctrl + + Ctrl + + to zoom in. Unfortunatly every new tab, or new window, defaults to the 100% teeny tiny zoom level. Is it possible for either: Chrome to respect my Windows dpi setting? Chrome to remember my zoom preference? Keywords: chrome, high dpi, accessibility Checked version: 4.0.249.78

• Use Windows Briefcase from the command line

  - by Daniel

  I have a thumb drive on which I take many of my files with me. I would like to synchronize it with my computer automatically when I connect it. I currently have a script run every time I connect it so that I can do the many things that need to be done when it connects (check for updates to the portable applications, etc.). I want my synchronization utility to: Detect conflicts work correctly when I move files or change the folder structure tell the difference between a file that was deleted on one side and a file that was added on the other work from the command line or at least have a command that will open up a window provide a confirmation screen before doing anything The Windows Briefcase does all of these except the command line. Is there any program that does all of these, or is there a way to synchronize the briefcase from the command line?

• Mixing RAM brands

  - by Andy

  Hey guys, I'm scheduled to install a server at a colo facility tomorrow, but I've hit a snag. ESXi doesn't like the fact that I have 12GB ram in my server (8gb on one side of CPU, 4gb on the other). I currently have 3xCrucial 4gb ECC DDR3 1333mhz sticks (http://www.amazon.com/gp/product/B001TGT7EE/ref=oss_product) and I'm planning on stopping by Fry's on the way to the colo facility so I can pick up another stick so that ESXi will install. Problem is, Fry's doesn't stock Crucial RAM. They do have a stick that I think is identical to my crucial one: http://www.frys.com/product/5915524?site=sr:SEARCH:MAIN_RSLT_PG Will this be dangerous to use in my server? The specs on the RAM are the same as far as I know (ecc registered, 1333mhz, ddr3, 4gb).

• How to troubleshoot intermittent and irregular connection errors on home network (preferrably Mac client)

  - by Martin

  Hi, I'm experiencing intermittent connection errors in our home network from two different computers, normally "Connection Reset" when browsing, but also other issues such as very slow throughput. I have approximately a network setup as below: ISP-Cable Modem-Dlink DIR 655 Router-(Ethernet)-Fon Router-Mac/Windows laptop Basically, is there a simple way to monitor the network and detect where issues are coming from? Right now we don't know if it is the Fon router, the Dlink router, the modem or the ISP. As the issue is intermittent, is there a software that regularly traceroutes a set of destinations and tests e.g. throughput, something that can help us figure out where in the chain the errors are introduced? The more automatic network monitor, the better.

• How reliable is HDD SMART data?

  - by andahlst

  Based on SMART data, you can judge the health of a disk, at least that is the idea. If I, for instance, run sudo smartctl -H /dev/sda on my ArchLinux laptop, it says that the hard drive passed the self tests and that it should be "healthy" based on this. My question is how reliable this information is, or more specifically: If according to the SMART data this disk is healthy, what are the odds of the disk suddenly failing despite this? This assumes the failure is not due to some catastrophic event that impossibly could have been predicted, such as the laptop falling down on the floor causing the drive heads to hit the disk. If the SMART data does not say the disk is in good shape, what are the odds of the disk failing within some amount of time? Is it possible that there will be false positives and how common are these? Of course, I keep backups no matter what. I am mostly curious.

• Sftp via shell - how it is possible

  - by Tomasz Zielinski

  (Moved from StackOverflow: http://stackoverflow.com/questions/4589725/sftp-via-shell-how-it-is-possible) How is it possible for tools like http://mysecureshell.sourceforge.net/ to provide SFTP access by merely specifying them as shell by typing: usermod -s /bin/MySecureShell myuser ? I'm on Debian Lenny, with default sshd/OpenSSH. Is this e.g. a feature of SSH protocol that allows user shell to handle sftp commands? I can't wrap my head around this because usually OpenSSH needs sftp-server module (or the internal one in newer versions) - and this makes me think that sftp commands don't even hit the shell and are handled earlier or by different code path..

• SMTP hacked by spammer using base64 encoding to authenticate

  - by Throlkim

  Over the past day we've detected someone from China using our server to send spam email. It's very likely that he's using a weak username/password to access our SMTP server, but the problem is that he appears to be using base64 encoding to prevent us from finding out which account he's using. Here's an example from the maillog: May 5 05:52:15 195396-app3 smtp_auth: SMTP connect from (null)@193.14.55.59.broad.gz.jx.dynamic.163data.com.cn [59.55.14.193] May 5 05:52:15 195396-app3 smtp_auth: smtp_auth: SMTP user info : logged in from (null)@193.14.55.59.broad.gz.jx.dynamic.163data.com.cn [59.55.14.193] Is there any way to detect which account it is that he's using?

• How can I check whether a volume is mounted where it is supposed to be using Python?

  - by Ben Hymers

  I've got a backup script written in Python which creates the destination directory before copying the source directory to it. I've configured it to use /external-backup as the destination, which is where I mount an external hard drive. I just ran the script without the hard drive being turned on (or being mounted) and found that it was working as normal, albeit making a backup on the internal hard drive, which has nowhere near enough space to back itself up. My question is: how can I check whether the volume is mounted in the right place before writing to it? If I can detect that /external-backup isn't mounted, I can prevent writing to it. The bonus question is why was this allowed, when the OS knows that directory is supposed to live on another device, and what would happen to the data (on the internal hard drive) should I later mount that device (the external hard drive)? Clearly there can't be two copies on different devices at the same path! Thanks in advance!

• How can I take browser screenshots at a higher resolution than my browser supports?

  - by Joshua Carmody

  I need to take a screenshot of a website as it would appear on a very high resolution monitor... say 4000x3000 pixels. My laptop's screen has a native resolution of 1400x768. Basically, I need to simulate having a monitor resolution much higher than my monitor and video card actually supports. I want the screenshot of the site to look pretty much how it does when you hit CTRL MINUS (zoom out) in Firefox repeatedly, but without any loss of pixels due to scaling. How can I do this? Is there some way to use virtual machine software to simulate a super-high-res display? If not, is there some way to open a browser window bigger than the screen, and then capture its contents as a PNG somehow? Anything else that might work?

• VMware ESXi 4 On-Disk Data Deduplication - possible and supported?

  - by hurikhan77

  Environment: We are running multiple web, database, and application servers which usually share a pretty common installation (gentoo linux) and similar configuration in VMware ESXi 4. The differences are usually only some installed features or differing component versions. To create a new server, I usually choose the most similar (by features) running server, rsync a copy of it into freshly mounted filesystems, run grub, reconfigure and reboot. Problem: Over time this duplicates many on-disk data blocks which probably sums up to several 10's of gigabytes. I suppose if I could use a base system as template with the actual machines based on top of that, only writing changed blocks to some sort of "diff image", performance should improve (increased cache hit rate) and storage efficiency should increase (deduplicated storage space). This would be similar to what ESXi already supports for RAM deduplication (page sharing). Question: Is there any way to easily do this on ESXi 4? I already share the portage tree via NFS but this would not work for the rootfs.

• Enabling the telnet client for all Windows 7 PCs on a domain

  - by ICTdesk.net

  The telnet client is disabled by default in Windows 7. I would like to enable the telnet client for all Windows 7 PCs in our domain. I know how to enable it manually: Start Control Panel Programs And Features Turn Windows features on or off Check Telnet Client Hit OK How can I do this for all Windows 7 PCs in the domain? All the Windows 7 PCs are in a separate OU. Can this be enabled by a registry setting that I can apply to all Windows 7 PCs? Can it be done by a Group Policy?

• Problem setting up DL360G5 with scsi RAID

  - by ernelli

  I have a problem with reinstalling OS on a DL360G5. The BIOS [F9] do not detect any disc controllers and the HP SmartSetup did not find any compatible controllers. Inside the server, the two SCSI disks are conncted to a RAID controller using BCM8603 chipset. How is disc contoller supposed to be setup? I have tried to do a full BIOS reset. EDIT At the moment we suspect that the Smart Array controller E200i/412205-001 is broken. Are there any status LED's that indicate failure or success during start up? At the moment all LED's are off.

• Capture RTSP stream from IP Camera and store

  - by Keerthi

  I've got a few IP Cameras which output an RTSP (h264 mpeg4) stream. Hitting the URL locally via VLC: rtsp://192.168.0.21:554/mpeg4 I can stream the camera and dump to disk (on my desktop). I'd like to however store these files on my NAS (FreeNAS). I was looking at ways to capture the RTSP stream and dump them to disk but I'm unable to find anything. Is it possible to capture the stream on FreeBSD or Linux (RaspberryPi) and dump the streamed content to a disk local to Linux or FreeBSD - preferably every 30minutes? EDIT: The NAS is headless (HP N55L or something) and the RaspberryPi's are headless too. I've already looked into ZoneMinder but need something small. I was hoping maybe using Motion to detect motion on the stream but that will come later.

• Provision storage in SAN encironment

  - by wildchild

  hi,.. Can somebody help in understanding how Lun Provisioning is done in clariion based on client requirement. Say, a client needs one 50 GB space on the host( for application) ,two -350 GBs ( for DB and stuff) on the same host and i have 4 raid groups with space of 200 GB in one 50 GB in second and 400 GB and 400GB in rest two all having 5 disks. And , I 'm using Raid 5 only. How do i provision keeping performance in mind( so that performance hit is not there)?..And i need to understand the concept of meta head as well. Please help me by elaborating the above scenario..I am learning to provision storage in non productive environment( b'fore going ahead and working on client prod server) and i have been learning a lot from SF ...I request the seniors here to help me understand it better.

• How do I burn Xubuntu Live CD

  - by Julian

  I downloaded the 600+ MB Xubunto ISO. Burnt it to a DVD using Nero Burning Rom, as a Bootable DVD. My bootup sequence won't detect XUbuntu and still only detects windows on my Hard Drive even after I set my BIOS to boot from the CDROM first. How do I burn the Live CD with Nero? I'm thinking maybe I should extract the contents and then burn the folder as data to my DVD. P.S: I only have DVDs lying around.

• OpenLDAP with StartTLS broken on Debian Lennny

  - by mr.zog

  I'm trying to get OpenLDAP on Lenny to work with StartTLS. I have a Fedora 13 machine which I'm using as a client for testing. So far the Fedora client is ignoring the 'host' directive in /etc/ldap.conf when I try to connect using ldapsearch. The client wants to connect to 127.0.0.1:389 even if I specify -H ldaps://server.name on when using ldapsearch. /etc/ldap.conf on the client machine is in mode 444. But even when I try connecting locally from an ssh session, I see errors like this: ldap_sasl_interactive_bind_s: Can't contact LDAP server (-1) Someone hit me with a cluebat, plz. Update: you must use ~/.ldaprc for settings such as 'host'.

• How do I keep the URL in the address bar when stopping page load in Firefox

  - by Peter Jaric

  Suppose I am visiting a page in Firefox and decide to go somewhere else and type the new URL manually into the address field, but the page fails to load, either because it times out, or because I hit Escape. Then Firefox removes my laboriously entered URL and replaces it with the URL of the current page. This is outrageous! I am pretty sure Firefox has changed this behavior lately, because this was one of the reasons I chose Firefox over IE back in the day. How can I turn off this annoying behavior? OS: Windows 7 Firefox version: 22

• Making GRUB see software RAID 0 under Ubuntu 10.10 LiveCD

  - by unknownthreat

  I just installed Windows 7 recently, and I expect that it would alter GRUB and it did. I've been following some guides around and I am always stuck at GRUB not able to detect the usual RAID content. (Software RAID 0) I've tried running: sudo grub > root (hd0,0) GRUB complains it couldn't find my hard disk. So I tried: find (hd0,0) And it complains that it couldn't find anything. So I tried: find /boot/grub/stage1 It said "file not found". So what now? How can we make GRUB see RAID 0 under Ubuntu 10.10 LiveCD?

• First time setting up a MySQL database.

  - by Wilduck

  In trying to learn how to work with the LAMP stack, I've hit a wall with MySQL. I can't seem to find a good reference for the first time setup of MySQL to be used with Apache and python. So, my question is four-fold: 1) Under what circumstances should I create my first database. That is, what user do I use (Apache's http user? root?) 2)How do permissions work? 3) Do I have to do anything on the MySQL side to make MySQL talk to Apache, or MySQL to talk to Python/Django? 4) Is there a good resource online that describes setting all of this up? I've found a bunch for using a database once it's in place, but none for the initial setup? Notes: I'm trying to run my LAMP stack on a dedicated little box for testing/learning purposes only, so I don't have access to any DBA that could help me, as much as I'd like one.

• I've created a software RAID on SUSE EL 10 and now I need to monitor it.......

  - by Thomas B.

  I have created a Software Raid using the yast2 GUI on SUSE ES 10/11. The raid works great and it's a raid 5. I have 5 Drives they are cheap 2GB Cases that have 2 - 1TB Drives in each case (Serial ATA Drives) and I connect them in via Esata to the motherboard. The problem I have as this is "cheap" storage when of the the 5 drives goes out on the RAID I seem to have no logs of any issues and it get's harder and harder to write to it until it dies. I use SAMBA to mount the 4TB parition to my PC's in my home on a GIG network. My question is this, are there any good (Free) tools in Linux to monitor a raid or the drives on the raid to detect any problems??? I haven't found any yet and was just wondering if some exist.
